Abstract
A system for drilling a well comprises a drill string in a wellbore having a bit at a distal end thereof. At least one sensor measures a drilling parameter. A computer controller has a set of instructions stored therein to process the measured drilling parameter over a drilled interval to calculate, in substantially real time, an updated friction slope and an updated worn bit slope and to calculate an updated drilling parameter for at least a portion of the well-based on the updated friction slope and the updated worn bit slope.
